26、ecimen is rigidly clamped and an axial compressive load is applied to the cable. 4 Apparatus 4.1 General The test apparatus shall be capable of applying an axial compression load between a clamped specimen and a cable. The apparatus consists of the elements described in 4.2 to 4.5. 4.2 Clamping devi
27、ce A suitable clamping device which grips a length of fibre optic cable over a distance equivalent to at least three times the cable diameter (see Figure 1, Dimension A), and which is capable of providing an axial load without slipping, causing damage to the cable or increasing attenuation. 4.3 Fixe
28、d clamping device A fixed clamping device capable of gripping the specimen without altering any of its mechanical properties. BS EN 61300-2-11:2013 6 61300-2-11 IEC:2012 4.4 Force generator A force generator may be any device or apparatus capable of smoothly applying the specified force at the speci
29、fied rate. 4.5 Force gauge A suitable instrument for measuring the applied force being exerted between the specimen and the fibre optic cable. 5 Procedure 5.1 Prepare specimens The specimen shall consist of a fully assembled optical component, prepared in accordance with the relevant specification.
30、Unless otherwise specified, the specimen shall be subjected to the following test procedure in non-operational mode. 5.2 Pre-conditioning Unless otherwise specified, pre-condition each prepared specimen for 2 h at the standard test conditions specified in IEC 61300-1. 5.3 Mount the device under test
31、 Securely fix the device under test to the fixed clamping device. See Figure 1 for an example of the test set-up. Clamp the cable at the point of application using a clamping device such that the distance, L, between the rear of the strain relief and the front of the cable clamping device is twice t
32、he cable diameter. The length, L, shall be at maximum two times the cable diameter to prevent cable buckling.

The position of the point of application shall be such that the load is axially transmitted. BS EN 61300-2-11:201361300-2-11 IEC:2012 7 5.5 Post-test examinati
34、on Remove the axial compressive load from the specimen and the specimen from the test mounting. Unless otherwise specified, visually examine the specimen and its component parts in accordance with IEC 61300-3-1. Check for evidence of cracking, permanent deformation or other damage which might impair
35、 its function, and against any other pass/fail criteria specified in the relevant specification. Careful attention shall be given to degradation of the optical signal, fibre breakage and excessive movement of the cable relative to the specimen. 6 Severity The severity consists of the magnitude of th
36、e axial compressive force. The severity shall be specified in the relevant specification. Recommended values of the test parameters are given in Table 1 and Table 2.
